To aZZ whom it may concern.-

vBe it known that I, FREDERICK Wnsrou, of Brixton, in the county ofSurrey, England, gas-engineer, have invented new and useful Improvementsin Apparatus Connected with Increasing the Illuminating-Power of CoalGas, (for which I have obtained patents in Great Britain, datedSeptember 24, 1880, No. 3,865, and in Germany, dated June 3, 1881, No.16,458,) of which the following is a specification.

The object of this invention is to improve apparatus wherein the gas iscarbureted and its illuminating-power greatly'increased by its beingcaused to come into contact with and absorb hydrocarbon fluids or otherliquids possessing the same or similar properties. I am aware it hasbeen proposed to use such apparatus wherein the liquid is taken up andheld in suspension by columns of sponge or other fibrous matter, and thegas, in its passage through or in between such fibrous matsuch liquid inthe form of vapor, and becomes thereby greatly enriched in quality andilluminating -power. Such apparatus consists,

mainly, of a reservoir for the hydrocarbon fluid, thecarbureting-chamber, an air-chamber within the latter, whereby theheight of the liquid within the carbureting-chamber may be regulated andbe fed automatically from the upper chamber or reservoir. An inlet-tubeis also provided for the gas to enter the chamber, an outlet for thesame after'it has passed through the carbureting-chamber, and in somecases a float to indicate' the height of the liquid.

My improvements consist in so constructing the carburetingchamber thatits efficiency in carburetin g and improving the gas is greatlyincreased. This I do by dividing the cham her into passages, and thesepassages I line on either or both sides with sponge or other fibrousmatter, so that the gas, in passing through the same, cannot fail in itscourse to be cleansed, and the spongy or fibrous matter more effectuallytakes up or absorbs and holds sus pended the liquid to be taken off invapor by the gas.

the reservoir, at the opening thereof.

,In order that the nature of my said inveir tion and the manner in whichthe same is to be carried into practical effect may be particularlydescribed and ascertained, this spec-ification is accompanied by a sheetof drawings having figures and letters of reference marked thereupon.

Figure 1 is a horizontal section on line V \V of Fig. 2, which is asectional elevation of my apparatus. A is the reservoir; .13, thecarburetingchamber; O, the air-chamber; D, the inlet-tube for the gas;E, the outlet for the same after it has been enrichedby the hydrocarbon.The spongy or fibrous matter lining the passages of thecarburetingchamber is marked F. The passages themselves are denoted bythe letter G. The plug of valve for the admission of the hydrocarbonfrom the reservoir A to the carbureting-chamber B is marked H, the seatH, the supply-tube to carburetingchambcr H The valve-plug is carried, asshown, at one end of a lever, I, and is providedwith a guide-spindle, J,working vertically in the arm K. To the other end of lever I is secureda vertical spindle, L, provided, as shown, with a spiral spring, M. Thisspindle extends upward to the screwcap N, into a recess of which itsupper end enters. The hydrocarbon fluid is supplied to the reservoir Aby the unscrewing of the cap N. When the screw-hole in the cover of apparatusis opened, the pressure of the cap is removed from the spindle,the spring M presses the vertical spindle upward, and thereby operatesthe lever I and closes the valve H H. The hydrocarbon fluid is thenpoured into the reservoir A, and then by replacing the cap N the spindleL is forced down, depressing the lever I and opening the *alve. In somecases I may prefer to dispense with the lever I and attach the plug ofvalve directly onto the spindle L. It will be apparent that the valve isonly necessary when the cap is opened, and is not required in any wayfor the proper action of the apparatus. The air-chamber is open at thebottom and its 1 edge is on the same level as the supply-tube. Thus whenthe and thereby cleansed and purified, and takesup a certain quantity ofthe hydrocarbon fluid. Thence, purified and enriched, it passes outthrough tube E, ready for consumption.

Fig. 3 shows in side elevation; Fig. 4 in longitudinal vertical section,and Fig. 5 in horizontal section through the line .90 y of Fig. 4, theapparatus as before described as applied to a lamp suitable for domesticpurposes, offices, and other places. A is the reservoir, B thecarbureting-chamber, G the air-chamber, D inlet-tube for the gas, Eoutlet-tube for same, all as before described. II is the valve foradmission of hydrocarbon from reservoir A to the chamber B. This valve His carried on the end of spindle'J, which is supported by bracket I, andextends upward; to the screw-cap N. M is a spiral spring to carry up thevalve-rod and valve when the screwcap N is removed. Coal-gas is admittedto the carbureting apparatus by the pipe 0, which may be supplied withgas through a flexible tube coming from any convenient source. Theaction of the apparatus is pre cisely similar to that before described.

I am aware that prior to the date of my invention carburetors embodyingthis principle under various forms were in use-such as that shown inpatent of T. Varney, No. 15,829, granted September 30,1856-and thereforedo not claim such construction, the novelty of my invention cons'stingin the. special arrangement and cons ruction of parts hereinafter setforth in the claims.

I claim I 1.. In a carburetor, the combination of reservoir A,air-chamber G, and carburetingchamber B, with its supply-tube D,arranged as de scribed, whereby the airchamber may be sealed and apressure created therein sufficient to counteract the weight of thehydrocarbon fluid in the reservoir, substantially as described.

2. The combination of the hydrocarbonchamber, the air-chamber, and thecarbureting-chamber, consisting of a series of concentric walls having alining of fibrous absorbent material, and openings in said walls,substantially as described, whereby circuitous passages are provided forthe fluid, as set forth. 3. In a carburetor, the device for filling orreplenishing the reservoir A, consisting of valve H and its stem, therock-lever I, slotted at its ends, rod L, with its spring M, and cap N,the whole being constructed to act in combination with the air-chamberG, substantially as described.
